Now, when you go to a certain shopping mall, you can enjoy its free WiFi there. When you want to take a taxi, you can book one with your phone. In fact, all these can be seen as the basic parts of a smart city. The idea of a smart city was brought up by US pany IBM in 2010. Generally, a smart city is a city that uses digital technologies such as the Internet to improve city planning, save money and resources, and make our life convenient. How smart can a city be? Here are great examples that we can learn from. In 2009, Dubuque became the first smart city in the US. The city used smart water meters to take the place of traditional water me tens. They can detect （探測） water waste and leakage （泄漏） and send data to let the house owner know. The same system is used for other city resources like electricity and natural gas. In this way, people know how they use their resources and are glad to help reduce waste. Santander in Spain also gives us a look at the future. If people point a phone toward a nearby bus stop, the phone immediately shows all bus lines that serve the stop as well as their arrival times. The government organized a research team and provided an App （應(yīng)用程序） that collects data on almost everything: light, temperature, and the movements of cars and people. Opening the App near a supermarket provides immediate information on special offers.（1）The underlined word convenient is closest in meaning to ______.

They stood in a circle, with 30 more stones lying on top to form a ring of rocks. There was also an inner circle built with similar stones. The stones set up in a trilithon（巨石牌坊） pattern. A trilithon is made of two stone pillars with a stab of rock laid across the top. The stones weigh up to 20 tons each. People wonder how the huge rocks were placed that way. Historians agree that Stonehenge was built in three different stages. The first stage took place about 5, 000 years ago. At that time, a large circular earth wall was made. Historians believe the wall was dug and cut with tools made form anglers（鹿角） of red deer. The earth wall was about 98m in diameter（直徑） a 5metertall stone was placed near the center. Then, they had to transport the large blue stones （up to 4 tons） 384 kilometers to Stonehenge. Experts think they might be moved across ice and snow. The ground in winter in this area is usually full of ice and snow, making it easier to move the rocks. The next task was to stand the stones up. The most difficult task was putting the top stones in place. Each one of these tasks took a lot of planning and a lot of strength, but the workers of Stonehenge were excellent builders. Why was the monument built? Some scientists think it39。s a burial ground. There are over 400 graves （burial sits） nearby. A man was buried with two gold earrings which are the oldest gold ever found in Britain （dated to 2470 BC）. Others think Stonehenge was built by early astronomers. Scientists believe that when a person stands in the center of the monument, the changing of seasons can be seen. Certain stones mark the location of the rising and setting moon in midwinter. Other stones mark the rising and setting sun in midsummer. The ancient people held religious ceremonies on these days. These ceremonies probably asked the gods to bring good weather for crops and to protect the people from bad weather. Stonehenge is an engineering success. Thousands of years later, it still stands. As a calendar, Stonehenge is very accurate. It shows that early people had a deep understanding of the movements to the sun and the moon. They didn39。t have machines or puters, but Stonehenge shows people could do many things using only their muscles and their brains.（1）he first building stage of Stonehenge was ________.

What is the sky? How high is it? What color is it? What birds can live above it? These questions are difficult to answer, aren39。t they? In fact, the sky has no color. Then why does the sky look blue? We know that there is air around the world. When planes fly, they need air to lift their wings. Planes can39。t fly very high. That is because the air gets thinner
